SAR125844 is a potent and selective inhibitor of the c-Met kinase receptor. This was an open-label, phase I, multicenter, dose-escalation, and dose-expansion trial of SAR125844 in Asian patients with solid tumors, a subgroup of whom had gastric cancer and MET amplification (NCT01657214). SAR125844 was administered by intravenous infusion (260-570 mg/m2) on days 1, 8, 15, and 22 of each 28-day cycle. Objectives were to determine the maximum tolerated dose (MTD) and to evaluate SAR125844 safety and pharmacokinetic profile...

Mature cystic teratoma is the most common kind of ovarian germ cell tumor. Malignant transformation is uncommon, with thyroid cancer rarely found. Papillary thyroid microcarcinoma has rarely been described as associated with ovarian teratomas. We report a case of a 34-year-old woman who presented with abdominal pain and an ovarian mass. After surgery, the patient was diagnosed with a follicular variant papillary thyroid microcarcinoma that arose within a mature cystic ovarian teratoma. Based on the small size of the primary lesion and patient preferences, no further treatment was performed...

Chromophobe renal cell carcinoma (chRCC) typically shows ~7 chromosome losses (1, 2, 6, 10, 13, 17, and 21) and ~31 exonic somatic mutations, yet carries ~5%-10% metastatic incidence. Since extensive chromosomal losses can generate proteotoxic stress and compromise cellular proliferation, it is intriguing how chRCC, a tumor with extensive chromosome losses and a low number of somatic mutations, can develop lethal metastases. Genomic features distinguishing metastatic from nonmetastatic chRCC are unknown. An integrated approach, including whole-genome sequencing (WGS), targeted ultradeep cancer gene sequencing, and chromosome analyses (FACETS, OncoScan, and FISH), was performed on 79 chRCC patients including 38 metastatic (M-chRCC) cases...

Primary cilia are chemosensors that play a dual role to either activate or repress Hedgehog signaling, depending on presence or absence of ligand respectively. While inhibition of ciliogenesis has been shown to be characteristic of breast cancers, the functional consequence is unknown. Here, for the first time, inhibition of ciliogenesis led to earlier tumor formation, faster tumor growth rate, higher-grade tumor formation and increased metastasis in the polyoma middle T (PyMT) mouse model of breast cancer...

System xc- is a sodium independent electro-neutral transporter, composed of a catalytic subunit xCT (SLC7A11) which is involved in importing cystine. Certain cancers such as gliomas up-regulate the expression of system xc- which confers a survival advantage against the detrimental effects of reactive oxygen species (ROS) by increasing the generation of the antioxidant glutathione. However, ROS have also been shown to function as targeted, intracellular second messengers in an array of physiological processes such as proliferation...

BACKGROUND: Chemotherapy and radiotherapy for breast cancer may lead to cardiac dysfunction, but the prevalence of long-term echocardiographic evidence of cardiac dysfunction is unknown among survivors. METHODS: In a cross-sectional study in primary care, we included 350 women who survived breast cancer for at least 5 years after diagnosis (treated with chemotherapy and/or radiotherapy) and 350 matched women (age and primary care physician). The primary outcome was cardiac dysfunction, defined as a left ventricular ejection fraction (LVEF) < 54% and an age-corrected decreased left ventricular (LV) diastolic function...

Background: Detailed information regarding the clinical efficacy of radiotherapy (RT) for primary tumor in patients with unresectable pancreatic neuroendocrine tumors (pNETs) is unknown. We therefore performed a retrospective study to evaluate the efficacy and safety of RT for primary pancreatic tumors in patients with pNETs. Methods: We investigated 11 patients with pNETs who received RT to the primary site between January 1997 and June 2015. Seven patients had Grade 2 neuroendocrine tumors (NET-G2) and four had neuroendocrine carcinoma (NEC) according to the 2010 WHO histopathological classification...

Triple synchronous primary malignant neoplasms are rare. The exact aetiology is unknown; however, risk factors include older age, family history, genetic aberrations, prolonged exposure to carcinogens and smoking. We describe a previously healthy 48-year-old woman who presented with abdominal pain and a palpable abdominal mass. Imaging revealed a complex cystic, solid pelvic mass and another mass in the right upper quadrant. She received an extensive abdominal surgery including exploratory laparotomy, pelvic mass resection, total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymphadenectomy, omentectomy and right adrenalectomy...

BACKGROUND: Current therapies for bone cancers - either primary or metastatic - are difficult to implement and unfortunately not completely effective. An alternative therapy could be found in cold plasmas generated at atmospheric pressure which have already demonstrated selective anti-tumor action in a number of carcinomas and in more relatively rare brain tumors. However, its effects on bone cancer are still unknown. METHODS: Herein, we employed an atmospheric pressure plasma jet (APPJ) to validate its selectivity towards osteosarcoma cell line vs...

BACKGROUND: Despite satisfactory efficacy of WHO-recommended second-line antiretroviral treatment for patients with HIV in low-income countries, the need for simplified, low-cost, and less-toxic maintenance strategies remains high. We compared boosted protease inhibitor monotherapy with dual therapy with boosted protease inhibitor plus lamivudine in patients on second-line antiretrovial therapy (ART). METHODS: We did a multicentre, randomised, parallel, open-label, superiority, trial in the HIV services of five hospitals in sub-Saharan Africa (Yaoundé, Cameroon; Dakar, Senegal; and Bobo Dioulasso, Burkina Faso)...

Skin damage induced by UVR is an escalating problem in dermatology, and increasing incidence of skin cancer, especially for non-melanoma skin cancer, has been reported worldwide. UVR from sun exposure and the production of reactive oxygen species (ROS) is known to be a pivotal factor in the aetiology of skin cancer. The pineal hormone melatonin is recognized as the most potent endogenous antioxidant. Melatonin conducts its antioxidant effects acting directly as a radical scavenger and indirectly by up regulation of antioxidant enzymes...

The main purpose of the TNM system is to provide an anatomic-based classification to adequately depict cancer prognosis. Accurate cancer staging is important for treatment selection and outcome prediction, research design, and cancer control activities. To maintain clinical relevance, periodical updates to TNM are necessary. The recently published 8th edition TNM classification institutes the following changes to the staging of head and neck (excluding thyroid cancer): new stage classifications [HPV-related oropharyngeal cancer (HPV+ OPC) and soft tissue sarcoma of the head and neck (HN-STS)] and modification of T and N categories [T and N categories for nasopharyngeal cancer (NPC), T categories for oral cavity squamous cell carcinomas (OSCC), N categories for non-viral related head and neck cancer and unknown primary (CUP), and T categories for head and neck cutaneous carcinoma]...

BACKGROUND: High levels of tumor-infiltrating lymphocytes (TILs) in primary triple negative and HER2-positive breast cancer (BC) have been associated with an improved patients' outcome. The role of TILs in Luminal (hormone receptor positive and HER2 negative) tumors remains to be elucidated. Moreover, the association between TILs and prognosis in the metastatic setting is still unknown. PATIENTS AND METHODS: We evaluated the relationship between TILs and time to progression (TTP) in metastatic BC patients enrolled in a prospective phase II trial of metronomic chemotherapy, that used cyclophosphamide 50 mg daily, capecitabine 500 mg thrice daily and vinorelbine 40 mg orally three times a week (VEX combination)...

BACKGROUND: Erosive pustular dermatosis of the leg (EPDL) is a poorly understood entity first described by Lanigan and Cotteril in 1987. Its clinical diagnosis is based on exclusion since the physiopathology is unknown. The primary objective of this investigation was to specify the clinical aspects and outcomes in a prospective study. The secondary objectives were to describe associated diseases, the circumstances of occurrence, and the laboratory tests used. PATIENTS AND METHODS: This was a prospective study that included 45 patients selected by members of the Angiology-Dermatology Group of the SFD (French Dermatology Society) at 13 centres between 01/09/2013 and 31/10/2014...
